Abstract

A flashlight has a housing, a light source in the housing, a power source in the housing, and a switch having a magnetically attractable actuating element in the housing movable between an on position for connecting the power source to the light source and an off position for disconnecting the power source from the light source. A control element shiftable on the housing between a pair of end positions carries a magnet juxtaposable through the housing wall with the magnetic actuating element such that movement of the control element between its end positions shifts the actuating element between its on and off positions.

Claims

1. A flashlight comprising:

a housing;

a light source in the housing;

a power source in the housing;

switch means including a magnetically attractable actuating element in the housing movable between an on position for connecting the power source to the light source and an off position for disconnecting the power source from the light source;

a control element shiftable on the housing between a pair of end positions;

a permanent magnet mounted on the control element and juxtaposable with the magnetic actuating element such that movement of the control element between its end positions shifts the actuating element between its on and off positions.

2. The flashlight defined in claim 1 wherein the housing is generally cylindrical and nonmagnetic.

3. The flashlight defined in claim 2 wherein the control element is a ring annularly surrounding the housing.

4. The flashlight defined in claim 1 wherein the actuating element of the switch means is also a magnet.

5. The flashlight defined in claim 4 wherein the actuating element is shiftable with the control element relative to the switch means.

6. The flashlight defined in claim 4 wherein the switch means is a reed switch.

7. The flashlight defined in claim 1 wherein the switch means is a dimmer.

8. The flashlight defined in claim 1 wherein the light source includes at least one light-emitting diode.

9. The flashlight defined in claim 1 wherein the light source is of variable intensity and the switch means varies the intensity of the light source.
